The Snake Catcher was an ancient Chinese novel written by Han Yu, a writer of the Tang Dynasty. This novel mainly tells the story of a snake-hunter and a snake. It reflects the author's concern and respect for life and nature, as well as his disgust for the illegal killing of wild animals. The Snake Catcher theory reflected the author's appreciation of life and nature. In the novel, the snake hunter couldn't help but sigh when he saw the snake." This is a big snake. It's too big!" He emphasized the preciousness of life and the beauty of nature, calling on people to respect nature and protect the ecology. Snake Catcher also reflected the author's dislike of illegal hunting of wild animals. In the novel, the snake-hunter was unwilling to catch his own kind. He emphasized,"Snakes are harmful. You can't catch too many." He expressed the importance he attached to the protection of wild animals and his strong opposition to illegal activities. The snake-hunter theory reflected some of the reality of society at that time. In the Tang Dynasty, snakes were an important wild animal. People often hunted snakes for food. In addition, snakes were also considered harmful animals and were often forbidden to be killed. Therefore, the Snake Catcher theory not only reflected the author's thoughts and feelings, but also reflected the reality of the society at that time.
